Constitutive Promoter + RBS + fMt


Figure 1. J23119+RBS+fMt



Introduction

      This sequence is designed for constitutively chelating arsenic ions. We ligated a constitutive promoter(BBa_J23119) with metallothionein (fMT, BBa_K190019) to produce arsenic-binding protein. This metallothionein (fMT) is a kind of chelating protein from Fucus vesiculosus. It can bind both Arsenite (III) and Arsenate(V). This part was first designed by Groningen of iGEM 2009. The part of K190019 consists of fMT and RBS(ribosome--‐binding Site, for initiating translation).

Modifying and Improving the Existed Biobrick

Previous biobrick BBa_K190031 of 2009 iGEM10_Groningen


      The metallothionein (BBa_K190031) is a fMT(BBa_K190019) under control of a low constitutive promotor (BBa_J23109). We failed several times in replicating the ligation of these two parts. After sequencing BBa_K190031, BBa_K190019, and BBa_J23109, we found the constitutive promoter BBa_J23109 has two Spel restriction sites in the prefix.(Figure 2.) Thus, we decided to modify the biobrick by ligating fMT(BBa_K190019) with another constitutive promoter (BBa_J23119). The Figure 3 shows the electrophoresis of BBa_K190019 when its plasmid was cut by Xba I and Pst I. And the Figure 4 shows the electrophoresis of BBa_J23119 and BBa_J23109 when their plasmids were cut by Spe I and Pst I.
